no. 1 Embodiment approach

[0069] Such as figure 1 As shown, the first embodiment discloses a thermal system 10 . The thermal system 10 is mounted on a vehicle. The thermal system 10 provides an air conditioner for a vehicle or a temperature adjustment device for equipment mounted on a vehicle. When utilized as an air conditioner, thermal system 10 provides heating and / or cooling. When utilized as a thermostat, thermal system 10 provides a heat source for heating and / or a low temperature source for cooling. The thermal system 10 has a refrigeration circuit 20 . The refrigeration cycle 20 is a vapor compression type refrigeration cycle 20 that provides low temperature and high temperature by compressing refrigerant vapor. The refrigerant is also referred to as the first heating medium. Further, the thermal system 10 has an auxiliary system 30 through which a heat carrier that exchanges heat with the refrigerant of the refrigeration cycle 20 flows. The auxiliary system 30 circulates cooling water as...

no. 2 Embodiment approach

[0107] This embodiment is a modified example based on the previous embodiment. In the above-described embodiment, convection is formed in the entirety of the inside of the core portion 41 . In this embodiment, instead, convection is formed in a part of the inside of the core 41 .

[0108] Such as Figure 9 As shown, the heat exchanger 40 has a connection member 245 as an inlet of water and a connection member 246 as an outlet of water on one end surface. The connection member 245 and the connection member 246 are arranged at corners located on the diagonal line of the upper end surface in the figure. These connection members 245, 246 extend in parallel. The connection members 43 and 44 are respectively arranged in a dispersed manner on both end surfaces of the core portion 41 . The connecting members 43 and 44 are collectively arranged on one side in the lateral direction. Furthermore, in this embodiment, the division board 241c is used.

[0109] Such as Figure 10 As sho...

no. 3 Embodiment approach

[0112] This embodiment is a modified example based on the previous embodiment. In the above-described embodiment, the partition plates 41c, 241c are used. In this embodiment, no compartmentalized panels are used.

[0113] Such as Figure 11 As shown, the heat exchanger 40 has a connection member 43 and a connection member 46 on one end surface. Furthermore, the heat exchanger 40 has a connection member 245 and a connection member 344 serving as an outlet of the refrigerant on the other end surface. In this embodiment, no compartmentalized panels are used. Therefore, all of the plurality of passages 41rf formed in the core 41 are connected in parallel between the connection members 43 and 344 . Since the connecting members 43 and 344 are dispersedly arranged on both surfaces, an S-shaped refrigerant flow path is formed in the core 41 . All of the plurality of passages 41wt formed in the core 41 are connected in parallel between the connection members 245 and 46 . Since th...

Abstract

The stacked heat exchanger has a core (41, 61) comprising a plurality of plates (41a, 41b, 641b, 41c, 241c, 741c, 41d, 41e, 61e) stacked to form a cooling Agent passage (41rf) and heat carrier passage (41wt). The first connection member (43, 543, 44, 344, 63, 64) provides an inlet and an outlet for the refrigerant to flow in the refrigerant passage (41rf). The second connecting part (45, 46, 245, 246, 745, 746, 47, 48, 65, 66, 67, 68, 967, 968) provides the heating medium to flow in the heating medium passage (41wt). The inlet and the outlet are used, and the heating medium flowing in the heating medium passage (41wt) becomes convective with respect to the refrigerant flowing in the refrigerant passage (41rf). The core includes offset fins (41f) provided at least in the refrigerant passage (41rf).

Description

[0001] This application is based on Japanese application No. 2013-37466 filed on February 27, 2013 and Japanese application No. 2013-191695 filed on September 17, 2013, and the contents of the description are incorporated herein by reference. technical field [0002] The present invention relates to a laminated heat exchanger for exchanging heat between a refrigerant and a heating medium in a refrigeration cycle. Background technique [0003] Patent Documents 1 to 6 disclose laminated heat exchangers. In particular, Patent Document 1 discloses a water-cooled laminated heat exchanger that can be used as a condenser. [0004] In the laminated heat exchanger disclosed in Patent Document 1, refrigerant passages are formed between laminated plates, and unevenness is formed on the plates. However, such a shape cannot sufficiently perform heat exchange with the refrigerant. From such viewpoints and other viewpoints, further improvement of laminated heat exchangers has been demand...
